Throttle whistle?

[mp3deviant721]

Seems like the throttle on my 03 whistles in the morning when its really cold after its been sitting overnight. It only does it cruising steadily at 45-55mph with the throttle barely open. Let off the throttle or open the throttle more and it goes away. It does this until the engine warms up. I took the intake tube off and saw that the throttle plate is pretty dirty. You guys think that could be my issue? Any input is appreciated. Thanks guys.

I have seen it before. It's worth cleaning just because it's dirty.

Yeah. I'm gonna try that here when I get a chance. Just gotta order a throttle body gasket. I'll keep this thread updated.
